Yeah thought about that one too, but then it just involved too much effort for me to get up off my lazy ass and ask 4-5 other people, which is why I thought the "buddy" system works good, plus radios, and hey presto, even though we went through about a million sets of lights and still could not hear you on the radio, we still all made it there in one piece!
Organising 4-5 other "leaders" and breaking up the pack is a good idea, if you could be bothered and if you could find 4-5 people to do it. But then you'd have a lot of chatter on the radio on who is at the back of which group turning where and maybe a bit confsing, Just have someone right at the back with a decent radio and who makes sure no one gets left behind, a job I thought I did pretty well with the help of Erin, prolly without her, it would have made my job harder as my plea's for directions and updates on where to turn where and asking everyone to slow up _might_ have gone unoticed
Key points:
1. Always keep a skyline in your rearveiw mirror
2. Always have someone appointed last in the queue, with a radio who knows where to go and can call out to someone in the pack who is listening to slow down or ask for directions.
Easy peasy!
